Summary: Poly(alkylene hydrogen phosphonate)s with a number‐average molecular weight of about 3 000 Da were obtained by a transesterification of dimethyl hydrogen phosphonate with poly(ethylene glycol) (PEG 400) under microwave irradiation with a very short reaction time (55 min) relative to that of classical thermal heating (9 h). The structure of the resulting polymer was confirmed by 1 H, 31 P, and 13 C NMR spectroscopy. The molecular weight was determined by 1 H, 31 P{H} NMR spectroscopy, MALDI‐TOF, and GPC.The transesterification of dimethyl hydrogen phosphonate with poly(ethylene glycol).
